just filled up with ARCO gas and got out the street and it started sputtering and cutting out. Limp it to side of the road and couldn't get it started. Towed it home and hope to work on it this weekend. My first thought was timing belt since its hitting 120k but then it sounded mor like fuel pump not working. Anyone has had this happen and whats the best way to check if fuel pump is working> Your opinion matters.
